skeeter slipping

[Tomd27858]

SL 190 150 v-max hammer. 21 M Prop around 2900 rpms. Set-up is factory with the addition of a SE 300 foil.

When pulling skier around 20 mph----2900 rpms and turn fairly sharp. Skier behind so nothing really aggressive. It feels like the prop loses its bite in the water. Actually feels like it completely stops pulling. I can advance the throttle and it will rev up and finally catch. Pulls smooth through nice wide sweeping turns. Just where the creek isn't as wide I need to come around a little quicker.

that doesn't work well for pulling a skier.

Any advice?

do you have it trimmed up or down? Your props blowing out, if you're trimmed all the way down the only other solution I know is to lower your motor a little and see what it does. If you're not trimmed all the way down try trimming it on down before making your turn and see if that helps.

I am trimmed all the way down so I can stay on plane that slow. Hmmm. So how does one lower the motor?

I think you could benefit from getting a second prop just for pulling skiers. A Powertech TR04 in about a 19p or a Bravo One should hold better in the turns and give you more power out of the hole to pull skiers up. It wouldn't be a good fishing prop because you would probably turn too many RPMs with just a moderate load but for torque and handling and would get the job done.

took the words out of my mouth Junkie

But if you want to lower your engine you'll need to use a engine hoist. The motor is only held onto the transom with 4 bolts, just be sure and silicone around them when you put it back on to keep water from getting into your transom.

I am no expert by any means, but I would not go with lowering your motor as the first thing. You may lose too much performance with that. I would get the other prop as recommended. Just one nut and about 2 minutes and your good to go. I wonder though, why your boat is doing that. I have the SL180 with the F150 with the same SE 300 foil and I have no trouble like that. I am sure PSM207 will have something to say about this one when he gets on. Good Luck.

[Tomd27858]

thought it was odd also. Maybe PSM will have some insight. Did it a few times making sure it was trimmed down all the way etc and was around 2900 rpms.

lowering the motor on that boat a notch isnt going to cause him to loose much performance, I'd say maybe a 1/2 mph top end. My thought is its a cheaper solution to try than buying a prop, especially if he's not one to care about speed. Something I got to thinking about is IF a 4 blade would actually bite better in a really sharp turn? Reason I ask that is because obviously he's getting some turbulance off the bottom of the hull when he makes a sharp turn and the reason he's blowing out is because his prop cant get a bite in that turbulant water. The 3 blade M prop has a bigger diameter (longer blades) than a 4 blade will, so that makes me wonder if the longer bladed M prop cant reach down far enough to get a bite in clean water, how will a shorter bladed 4 blade prop be able to? You might post this over in the Set-Ups forum and see if Todd can give you some good insight on this. All we can do is guess, Todd will probably know what to do

Also, another reason I ask this is because I am running a 4 blade on my boat and it seems like I can make it slip in a hard turn easier than I could my original M prop. BUT, I also have this prop jacked up pretty high, so that could be part of it too.

Jay you answered your own question. Your 4 blade will slip in hard turns because you are running it so high. My TR04 will slip a little too in a really hard turn but I'm running it as high as I can. When I had it lower on the plate it held on tight. A blueprinted Bravo One will corner better than all of them due to it larger diameter. The 4 blades just have a little more overall blade surface which usually keeps them hooked up a little better.

You could call Jr at Pitstop Marine and see if he has a TR04 you can test. I think at one time he would loan them out for a small fee. Otherwise look around locally and see if you can find a good 4 blade to test. Most props shops have used props they will let you try for a minimal fee or a deposit.

Thanks for all of your input. Looks like I need to go prop shopping.
